61.8%. 46.2%.
72.8%. 27.2
54.6%. 45.4%
61.8%. 46.2%.
what gender is more likely to underestimate their weight?
women
what gender is more likely to overestimate their height?
men
what province has the lowest rate of overweight and obesity?
British Columbia (48%)
how many children between the age of 12-17 are considered obese?
23.1%
What province has the highest rates of obesity?
Newfoundland and Labrador
What disease are increased with people classified as overweight or obese?
Heart Disease, Stroke, High blood pressure, cancer Type 2 diabetes, gallbladder disease, osteoarthritis,sleep apneas
What is the difference between overweight and obesity
your weight is greater than the specific height (body builders) obesity means that there is an excessive accumulation of body fat which is associated with health risk (a women can not be overweight but be obese is 30% of weight is for body fat)
What is the criteria for obesity to be considered a disablitiy?
at least 45 Kg overweight or Bmi over 40 and underlying disorder causing obesity.
What is the calculation for BMI
weight (kg)/height (m)^2
When is BMI underweight? Appropriate weight? Overweight?
below 18.5 18.5-24.9 25.0-29.9
What BMI results in title of obese?
30
What is obese class I? II? III?
30-34.9/ 35.0-39.9/ 40.0
What two category is body mass broken down in to?
Fat free mass and fat mass
Types of fat?
essential and storage
What percent of essential fat do men have? Women?
3-7
10-15
Percent of storage fat to body weight for healthy Canadians
5-25 percent
What is a low limit for men? women?
3-4 percent
8 percent
What is critical level of necessary fat to maintain menstrual flow?
8-13 percent
Method of body composition assessment in which it estimate are made of bone mineral content and lean and fat mass using low energy and high energy photon beams
Hydrostatic weighing
Dual energy X-ray absorptiometry
Skin Fold measurement
Waist Circumference
Air Displacement Plethysmography
Dual energy X-ray absorptiometry
What does the skinfold measurement use for the device?
skinfold calipers
issues with skinfold measurement
will not work for obese people who have 20-40 percent of fat.
Primarily developed on young, white, healthy males
Where is wasit circumference?
iliac crest/ hip bone
circumference greater than what indicate increase risk of heart disease T2D, hypertension, hyperlipidemia for men? women?
102 cm and 88 cm
How does Hydrostatic weighing work?
measurement of displaced water when person is completely submerge because fat tissue has lower density than muscle or bone tissue
Problem with Air Displacement Plethysmography which is similar to hydrostatic weighing
Assumption that Fat free mass and fat mass is constant
bone mineral content density changes which varies throughout life cycle
Technique of body fat assessment in which weak electrical current is measured.
Hydrostatic weighing
Dual energy X-ray absorptiometry
Skinfold measurement
Waist Circumference
Bioelectrical Impedance Analysis
Air Displacement Plethysmography
Bioelectrical Impedance Analysis
